Kollam–Thiruvananthapuram trunk line is a railway line in Southern Railway zone connecting the cities of Kollam and Thiruvananthapuram in the state of Kerala, India. The line was opened on 4 January 1918 as the extension of Madras–Quilon line during metre gauge era.


South Indian Railway Company has opened the Quilon–Sengottai railway line in 1902 with an intention to connect Quilon (Kollam), the commercial capital of Travancore with Madras. Port of Quilon and the city's commercial reputation has urged the British rulers to connect the city of Quilon with Madras for the smooth transportation of goods including Pepper, Cashew, and spices.[3] Later on 4 January 1918, Thiruvananthapuram South Indian Railway Company has opened the Kollam–Thiruvananthapuram extension up to Chala. The terminus was shifted to Trivandrum Central (Thampanoor) and was inaugurated in 1931.[4]


This line falling under the administrative control of Thiruvananthapuram railway division of the Southern Railway zone connects with ThiruvananthapuramKanyakumari line in South, KollamKayamkulam line in North and Kollam–Punalur–Sengottai line in the East.[4][5]
